.Thisinventioir relates; to a. and improved: deflector? for: wagon. elevators and is used. morepartieularlyr for the; wagon. elevators. of. corn. pickers.

'IZhe purpose of a wagon elevator is. to convey crops from a harvesting implement. to. a trailing: wagon Atrailing; wagon has consid-. erable length. and; it is. necessary to. deliver the; harvested: 'graini evenly: throughout; that length in order to properly fill the wagon. The present: application isconcerned with the deliveryrof harvested. ears of cormfrom. at wagon elevator to. a trailing? wagon; In order to deliverthe': corn throughountherlengthoi the wagon, deflectors on the elevatorare a. necessary attachment. There have. been many: forms. of". deflectors utilized and yetzthera a. definite need fora. Wagon elevatordeflector: which wilhnot; injure" or causee'd'ama'ge. to, thexcorn. and 'yet: may be; adjustable so: that the trajectory-oiling corn; maybe variedthrough--- out: numerous. incrementsof changes fortheputposaoi. depositing corn: in any desired porti'on of the-wagon.

: Is: istherefore; aprincipal object oft-his .i-nven tiongto: provide :a deflectorfor wagon elevators. which: is.- sufiiciently yie-ldable. in its make-up so a'snotto: causedamage to. the material beingele vatedland discharged: to. a trailing-"wagon;

Another important obj ect. of this invention is to supplyawagonlelevator with an angularly adjustable deflector for the purpose of varying the efiective range of throw of the material being elevated thereby. I

. A still; further: important. object. of this invention is the provision of a flexible deflector for wagon elevators. capable. of. simultaneously yielding to minimize damage to cars ofcorn and to direct said ears of corn to various positions along thedengthofatrailing wagon. r

:Astilli. further important-object of this invenisjto providea. hinged canvas type deflector for. use theupper ends-of wa'gonelevato-rshavh1g weight meansv to normally hold the deflector extended and adjustable means to vary the angle of disposition of the canvas deflector within the upper end of an ear corn wagon elevator.

Other and further important objects of this invention will become apparent from the disclosures in the following specification and accompanying drawing.

In the drawing:

is adapted to: elevate ears ofi cor-n designated-by the numeral; I 1 received from: the-hopper l4? up-- wardly and rearwardly to adischarge end re of the wagon" elevator l5. and thereupon be. dropped into a relatively-long trailing wagontfl-i. The trailing wagon includes a box portionZ-il; rear wheels H, front v wheels 2'2, and a forwardly extending. tongue 'Z3Ladapted to be fastened to the: tractor draw-.barfil. Y r

The dischargeend t8 of the wagon elevator I5: includes a curtaimty-pe canvas deflector-1a hingedorra shaftzor-rod member 2-6 j'ourna'led in the. upper endsof side sheets 21 and 2% ot'the wagon. elevator as best-shown in Figure 2. The deflectorcurtaimzi: iszpreferably'madeof a can vas: or: other. flexiblematerial. which will notv in jure ears of corn as they strike the curtain. As shown in Figure 1 the deflector curtain25 is inclined substantiailyr vertically so. that: the ear of corn: striking. thereagainst. will be deflecteddowns. wardly into the iorwardiend of the. wagon box- 202' Figure..- 3 shows xan'ear-off'ocrn leaving the elea.

vator:--,conves:or wand striking theaconvaszcur-y tain 25s The curtain has yielded to the shape! of. thaear of cor-n insuring thatitlierelwillibeno damage-to; the'kernels of oorrr thereon. Y

A weight 29 is contained within a lower hem of the canvas curtain and thus by gravity the curtain will remain extended in substantially vertical position unless otherwise adjusted. The shaft 26 is provided with depending integral spaced apart arms 30 and 3| located between the side sheets 21 and 28. As the rod 25 is rotated within its journal support, the arms 38 and 3| thus swing through a similar degree of angular movement. Chains 32 and 33 are fastened to the lower ends of the arms 30 and 3| at 34 and 35. The other ends of the chains 32 and 33 are connected to the ends of the weight member 29 lo- 42 to the top of a fan housing 43 which in turn forms part of the corn picker l0. Stops 44 are fastened at intervals along the end of the connecting link 39 and are adapted to engage the locking bracket M for various adjustment of the operating arm 31. The rod 39 as shown in Figure 1 is in substantially its lowermost position permitting the canvas 25 to remain substantially vertical. As the rod 39 is pushed upwardly and rearwardly it may be held in any desired position by one of the lower positioned stops 44 in the bracket 4 I as shown in Figure 4 the canvas curtain 25 is angularly disposed upwardly and rearwardly so that ears of corn discharged from the conveyor [6 will be deflected toward the rear portion of the Wagon box 20 and thus the wagon may be loaded uniformly, throughout its length merely by the operator changing the angular disposition of the canvas curtain 25.

In operation the canvas curtain is adjusted throughout its angular range of movement by an upward and rearward movement of the link 39 which changes the angular position of the depending arm 31 of the rod 26. The chains 32 and 33 joining the lower ends of the arms 30 and 3| with the canvas curtain act to raise the curtain directly in response to angular change of movement of the arm 31. It will thus be seen that the canvas deflecting curtain of this invention per-.

forms its primary function of deflecting ears of corn to any desired position along the length of the wagon box and yet in all positions of adjustment the canvas deflector is yieldable and thus not injurious to the ears of corn by reason of its inherent flexible nature and further in view of the fact that the canvas is held in adjusted. position by collapsible chains 32 and 33. Ears of corn may thus be properly delivered from a corn harvesting machine to a trailing wagon. Various details of construction may be changed throughout a wide range without departing from the principles disclosed herein, and we therefore do not-propose limiting the patent granted hereon l by the appended for rotational movement in said side sheets, aflexible curtain fastened to said shaft, means for so adjusting the angular disposition of said flexible curtain, said means for adjusting the curtain in cluding a pair of spaced apart arms fixed to said shaft and inclined downwardly and rearwardly spaced from said curtain, and flexible means joining the lower end of said curtain to the lower end of each arm whereby rotation of the shaft causes an arcuate movement of the arms and a corresponding movement of the curtain.

' '2. A deflector as set forth in claim 1 in which the shaft extends outside one of said side sheets, an operating arm fastened to said shaft extension, and link means joining said operating arm for remote rotation of said shaft.

3. A deflector as set forth in claim 2 in which lock means is provided to hold the link means in adjusted position.

4. A deflector for wagon elevators of the typ having an upwardly and rearwardly inclined conveyor within a housing having spaced side sheets comprising a shaft extending across and journaled for rotation in said side sheets, a canvas curtain fastened to said shaft between said side sheets and disposed adjacent the upper end of .the elevator conveyor to act as a cushion for the material discharged from the conveyor and being deflected to a trailing wagon, a weight member inthe lower end of said canvas curtain to main-- tain it in extended position, and means for varyin the angular disposition of said canvas curtainp 5. A deflector asset forth in claim 4 in which;

the means for varying the angular disposition of the curtain comprises spaced apart arms fastened to said shaft in an angularly inclined :position spaced rearwardly of said curtain, said arms located on said shaft adjacent the inner side of each of said side sheets, flexible chain means joining the lower ends of the arms to the lower weighted end of the curtain,rsaid shaft having. an extension beyond one of said side sheets, an:
